Abstract

Machine (especially deep) learning algorithms are changing the way wildlife imagery is processed. They dramatically speed up the time to detect, count, and classify animals and their behaviours. Yet, we currently have very few systematic literature surveys on its use in wildlife imagery. Through a literature survey (a ‘rapid’ review) and bibliometric mapping, we explored its use across: 1) species (vertebrates), 2) image types (e.g., camera traps, or drones), 3) study locations, 4) alternative machine learning algorithms, 5) outcomes (e.g., recognition, classification, or tracking), 6) reporting quality and openness, 7) author affiliation, and 8) publication journal types. We found that an increasing number of studies used convolutional neural networks (i.e., deep learning). Typically, studies have focused on large charismatic or iconic mammalian species. An increasing number of studies have been published in ecology-specific journals indicating the uptake of deep learning to transform the detection, classification and tracking of wildlife. Sharing of code was limited, with only 20% of studies providing links to analysis code. Much of the published research and focus on animals came from India, China, Australia, or the USA. There were relatively few collaborations across countries. Given the power of machine learning, we recommend increasing collaboration and sharing approaches to utilise increasing amounts of wildlife imagery more rapidly and transform and improve understanding of wildlife behaviour and conservation. Our survey, augmented with bibliometric analyses, provides valuable signposts for future studies to resolve and address shortcomings, gaps, and biases.

Abstract

We present data on species composition, relative abundance and estimated densities for leaf-litter anuran amphibians from an Atlantic Forest area within the Parque Estadual do Desengano, in the state of Rio de Janeiro, Brazil, based on results of a short-term survey carried out during the winter at altitudes of 1000-1500 m. Three sampling methods were used: plot sampling, visual encounter surveys (VES; performed during the day, at the twilight, and at night), and pitfall traps. We recorded 13 species, with the direct-developer Ischnocnema parva (Girard, 1853) being the most abundant. Most frogs (ca. 90% of all individuals) sampled by VES were captured during the crepuscular and nocturnal periods. The estimated density of the local leaf-litter frog assemblage based on plot sampling was 13.2 ind.100 m-2, which is one of the highest values currently reported for Atlantic Rainforest areas. This is the first study analyzing the anuran fauna of the Parque Estadual do Desengano and adds to the knowledge of the fauna of the northern region of the state of Rio de Janeiro, which is still poorly studied. Apresentamos dados sobre a composição de espécies, abundância relativa e densidade estimada para anfíbios anuros de serrapilheira de uma área de Mata Atlântica no Parque Estadual do Desengano, no Estado do Rio de Janeiro, Brasil, com base em resultados de um estudo de curto prazo realizado durante o inverno a altitudes de 1000-1500 m. Três métodos de amostragem foram utilizados: amostragem em parcelas, encontros visuais (realizados durante o dia, no crepúsculo e à noite) e armadilhas de queda. Foram registradas 13 espécies, com Ischnocnema parva (Girard, 1853), uma forma com desenvolvimento direto, sendo a mais abundante. A maioria dos anuros (ca. 90% de todos os indivíduos) amostrados pelo método de encontros visuais foi coletada durante os períodos crepuscular e noturno. A densidade estimada para anuros de serrapilheira foi de 13,2 ind.100 m-2, que é um dos valores mais altos atualmente registrados para áreas de Mata Atlântica. Este é o primeiro estudo que analisa a fauna de anuros do Parque Estadual do Desengano e contribui para o conhecimento da fauna da região norte do estado do Rio de Janeiro, que ainda é pouco estudada.

Abstract

This study presents information on habitat use, diet, reproductive aspects of, and the helminth parasite community in, the frog Proceratophrys mantiqueira from an Atlantic Rainforest area (APA Mantiqueira) in southeastern Brazil. Frogs were collected at altitudes between 1200 and 1775 m. The estimated population density of P. mantiqueira in the area was 2.0 ind/100 m2, and the microhabitat most frequently used (82% of the individuals) was the leaf litter on the forest floor. The diet was composed by 20 types of prey items, with Coleoptera and Orthoptera contributing the most important items. The width of the mouth affected the volume of prey consumed by P. mantiqueira, as is expected for frogs, because they swallow their prey whole. There were ontogenetic changes in the types of prey in the diet of P. mantiqueira, with no ingestion of Coleopteran adults by juvenile frogs (< 26 mm). The clutch size of females of P. mantiqueira (692--923 eggs) was similar to those reported for the congeners P. appendiculata and P. tupinamba, but slightly smaller than those recorded for larger species of Proceratophrys such as P. boiei and P. caramaschii. Despite occurring at relatively low densities in the study area, P. mantiqueira had a high prevalence of infection by helminthes (90%), possibly because the helminth parasite community was mostly composed by host-generalists and monoxenous life-cycle species. Diet composition and rates of endoparasite infection, but not microhabitat use, changed with the age structure of the studied populations of P. mantiqueira. [ABSTRACT FROM AUTHOR]

Abstract

Effective and targeted conservation action requires detailed information about species, their distribution, systematics and ecology as well as the distribution of threat processes which affect them. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed in order to highlight urgent conservation cases and inform environmental policy with appropriate biodiversity information in a timely manner. We present the first ever global analysis of extinction risk in reptiles, based on a random representative sample of 1500 species (16% of all currently known species). To our knowledge, our results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Nearly one in five reptilian species are threatened with extinction, with another one in five species classed as Data Deficient. The proportion of threatened reptile species is highest in freshwater environments, tropical regions and on oceanic islands, while data deficiency was highest in tropical areas, such as Central Africa and Southeast Asia, and among fossorial reptiles. Our results emphasise the need for research attention to be focussed on tropical areas which are experiencing the most dramatic rates of habitat loss, on fossorial reptiles for which there is a chronic lack of data, and on certain taxa such as snakes for which extinction risk may currently be underestimated due to lack of population information. Conservation actions specifically need to mitigate the effects of human-induced habitat loss and harvesting, which are the predominant threats to reptiles.

Abstract

Estudamos as bromeliáceas do Parque Nacional da Restinga de Jurubatiba, Macaé, RJ, nas cinco diferentes zonas de vegetação: psamófila halófila reptante (PHR), fechada pós-praia (FPP), arbustiva aberta de Clusia (AAC), arbustiva aberta de ericácea (AAE) e mata periodicamente inundada (MPI). Analisamos abundância, densidade, biomassa, riqueza, diversidade, equitabilidade e similaridade de espécies entre as zonas. Estimamos a quantidade de água reservada no interior das bromélias por zona de restinga e por espécie de bromélia. Em 98 parcelas de 100 m² (10 X 10 m) cada, registramos as espécies de bromélias, a abundância de cada espécie e a zona amostrada. A quantidade de água armazenada e a biomassa das bromélias foram estimadas medindo-se o volume de água reservada no vaso e pesando 10 indivíduos por espécie. Encontramos 10 espécies na restinga de Jurubatiba, com densidade total estimada de 10386 ind.ha-1. Na zona PHR, não ocorreu nenhuma espécie de bromélia. Na FPP, ocorreu a maior biomassa total (7721,2 kg.ha-1), sendo Bromelia antiacantha a mais abundante e com maior biomassa (1366,5 kg.ha-1). Na AAE, ocorreu a maior densidade total (15725 ind.ha-1), diversidade (H’ = 2,358), equitabilidade (0,786) e quantidade de água reservada no interior de bromélias (3294,8 L.ha-1). Na MPI, Aechmea bromeliifolia foi a mais abundante, sendo exclusiva desta zona. A maior similaridade ocorreu entre AAC e AAE (88,9%). Concluímos que a estrutura e a composição de Bromeliaceae da restinga de Jurubatiba variam fortemente entre as zonas estudadas, com cada zona possuindo um conjunto particular de espécies com diferentes distribuições de abundância. We studied the bromeliads at the Jurubatiba National Park in five vegetation zones: psamophilous halophilous creeper vegetation (PHR); closed rear beach (FPP); open shrubby Clusia (AAC); open shrubby Ericaceae (AAE) and temporarily flooded forest (MPI). We sampled 98 plots of 100 m² (10 x 10 m) recording the bromeliad species and abundance, density, mass, richness, species diversity, evenness, and similarity among the zones. We estimated the amount of water reserved inside the bromeliads in each zone and by bromeliad species. We found a total of ten bromeliad species at the Jurubatiba National Park that occurred differently along the vegetation zones, with a total density of 10386 ind.ha-1. No bromeliads were found in the PHR zone. The FPP zone had the highest total mass (7721.2 kg.ha-1) and Bromelia antiacantha was the most abundant, having the highest mass (1366.5 kg.ha-1). The AAE zone had the highest total bromeliad density (15725 ind.ha-1), the highest bromeliad diversity (H’= 2.358), evenness (0.786) and amount of water reserved inside bromeliads (3294.8 L.ha-1). In the MPI zone, Aechmea bromeliifolia was the most abundant, being found exclusively in this zone. The highest similarity occurred between zones AAC and AAE (88.9%). We conclude that the structure and composition of the bromeliads at the Jurubatiba National Park varied consistently among the vegetation zones of the restinga, and each zone is characterised by a different set of dominant bromeliads and different abundance distribution.
